Abstract
A device for controlling a power supply of a radio frequency ignition of a combustion engine, including: an interface that receives measurement signals of operating parameters of a combustion engine; an interface that outputs a control signal; a module that stores relationships between measurement signals and the frequency of a control signal to be generated; a module that determines the frequency of a control signal to be generated on the basis of measurement signals received on the reception interface and of the relationships stored; and a module that applies the control signal at the determined frequency.
Claims11
A power-supply control device for a radiofrequency ignition of a combustion engine, comprising:
- a memory module that stores relationships between predetermined values of measurement signals of operating parameters from the combustion engine and frequencies of a control signal;
- a reception interface that receives current values of the measurement signals;
- a determination module that determines a desired frequency of the control signal as a function of the current values of the measurement signals received at the reception interface and of the relationships stored in the memory module;
- a generation module that generates the desired frequency of the control signal determined by the determination module;
- and
- an output interface to output the desired frequency of the control signal from the generation module to control the ignition.
